libusb_claim_interface failed on Windows7

I got a failed message when using `xusb.exe myvid:mypid`, and it failed when
claiming interface 2.
It shows like this:

  <http://libusb.6.n5.nabble.com/file/n5715986/failed.png> 

And usb_claim_interface is OK while using the libusb-compat-0.1.4 library.
But libusb-compat-0.1 API does not meet my requirement, I need to use
libusb1.0 API(libusb_get_port_number).
So, is it possible to use libusb1.0 API on Windows? The example is not
working well.
Anyone help? Thanks!
